UNITED svi-Aresv PATENT OFFICE/5 IVA M. 'C AIDDlEl'ifl'i, OF MARYVELLE, MISSOURI.

rlhis invention relates to demountable rims for motor vehicles and the like and its general object is to providea demountable rim that can be easily and expeditiously applied and removed from a tire in a minimum amount of time with very little efiort on the part of the operator and without the use of tools or the like. i

A further object of the invention' is to provide a demountable rim of the collapsible sectional type, that is extremely simple, durable and inexpensive to manufacture, and will securely maintain a tire in proper position thereon without `fear of collapsiin;y or causing damage to the tire, whether it be the pneumatic type or otherwise.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. y

ln describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a side elevation of a vehicle wheel showing my novel rim 1n operative position.

Figure 2 is a sectional view taken on line 2 2 of Figure l.

Figure 3 is an inner plan view of one section of my novel rim.

Figure lis a similar view of another section thereof.

Figure 5 is a perspective view of the locking band which forms a part of thepresent invention.

Referring to the drawings in detail theV letter A indicates a. vehicle wheel vwhich includes the usual felly B and the rim Vlugs C which operate to retain the rim upon the felly B as clearly shownv in Figure 2 Aof the drawings.

The above forms no part of the `present invention which resides solely in the rim v disclosed and said rim-includes a plurality of sections preferablyT three in number as shown and two of these scc-tions are of Vsimilar formation as indicated bythe referenceY numeral l while the remaining sect-ion is indicated by the reference' num ral 2 and has,

TIRE BEM.

Application filed August 17, SerialfNo. 213,547.r

vfrom its inner surface a tongueV 3 which i* formed with recess l adapted to accommodate one the-bolts as best shown in Fig ure 2 to prevent creeping of the rim upon its felly as will be readily apparent.

Each of the sectionsincluding the section 2 isV provided with asubs-tantially V-shaped tongue 5 formed on one end thereof as best shown in F igures. 3 and 4; of the drawings` and these'tongues 5 are adapted to be acconunodated in substantiaily' `\=-shaped ref cesses 6 formed on the opposite ends of the .eetions, when the said sec-tions yare asso-l ciated in rim formation shown in Figure l of the drawings. It'will be obvious that thistongue 5 and recess connection prevents lateral movement of the sections when so associated.

ln order to retain the sections in cooperative association, I provide an annular band 7 which is vof a diameterto snugly fit the in' ner periphery of the sections when they are arranged in rim lformation. The band 7 is provided with an opening 8 adapted to regis ter with the opening 9 in the rim section 2, and said band is further provided with a slot l0 to accommodate the tongue 3 as shown in Figure 2.

The rim sections are provided with the customary flanges 1l .and l2 upon their lopposite side edges so as to accommodate the tire beads in the usual manner as will be readily apparent.

From the above description and'disclosure inthe drawings it will be obvious that I have provided a demountable rim of theesectional type which includes a number of sections adapted to be associated in rim formation and held in such formation through the instrumentality of the band 7. By this construction, the rim can be easily and eX peditiously applied and removed from a tire with very little effort and in a minimum amount of time it being apparent that all that is necessary in applying the rim to a tire is to insert the rim sections l and 2 in rim formation therein with the tongues 5 sov in their companion recesses 6V and then apply i v the hand 7 inthe manner as abover set forth.

It is thought from the jforegoing description that lthe advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combinationand arrangement of the several parts, provided that suoli changes fall With-inV the scope of the appended claim.

What I claim is: Y A rin'i of the character described compris- 5 ing a plurality of sections arranged in end to end relation in riin formation, tongues `termed on each of said sections and received in recesses also formed therein, tire beadl ilanges formed With the side edges of each 10 section, a recessed tongue extending centrally and inwardly from one of said sections, an annular band formed With a slotr receiving said recessed tongue and securing said sections in riin formation, and said last mentionedv section and band respectively being provided with openings arranged in registration.

In testimony whereof I affix my signature.
